Abstract

Verfahren zur Herstellung metallischer Bauteile die eine Öffnung (3) und/oder einen Hohlraum umfassen durch selektives Lasersinter- und/oder Laserschmelzen wobei schichtweise ein- oder mehrkomponentiges metallisches Pulver an entsprechenden Querschnittsbereichen durch Einsatz von Laserstrahlung aufgeschmolzen wird wobei das Bauteil nach dem Lasersinter- und/oder Laserschmelzvorgang einem Bruchtrennprozess unterzogen wird, bei dem das Bauteil entlang einer Bruchlinie (4) in mindestens zwei Bruchteile (1, 2) gebrochen wird und danach die wenigstens zwei Bruchteile (1, 2) an ihren Bruchstellen zur Bildung des Bauteils miteinander verbunden werden wobei die Bruchlinie (4) zumindest bereichsweise die wenigstens eine Öffnung (3) und/oder den wenigstens einen Hohlraum berührt und/oder durchsetzt.
